Paywave cards are now accepted on London buses (in a very basic
configuration, no daily capping, no use on the tube), as an alternative
to Oyster.
If a ticket inspector wants to check your Oyster card on the bus to see
if you have paid, then it contains a recent journey history (10
transactions I think).
Do Paywave cards have any history stored on them - even as minimal as
the time/date/amount of the most recent usage?
